Use Gmaptool to install maps images in Mapsource
(...)NOTE:Remember this kind of mapsource installation wont give you search capabilities
From GmapTool Help: "Unfortunately GMapTool is unable to convert a MDR file form mapset into a format acceptable by Mapsource. Do not bind this file to Mapsource, it will not work properly."

What it means? That I wont be able to chose journey destiny by searching specific address (Country, City, Street, Building Number)?

Advertissements

It means that you maybe can use 'search nearest' for POIs but not specific addresses.

I have a question about the process of converting .IMG files into MapSource-compatible .IMG sets - actually it's more about the resultant maps and how they are appearing in MapSource (v6.16.3).

I successfully downloaded and unlocked BlueCharts "HPC024R - Australia & New Zealand v2012 (v13.50)", which was a single 850+MB .IMG file.

I then followed the instructions in this thread and installed the relevant apps/utils on my PC (Win 8.1 Pro, 64-bit) and converted the single .IMG file
into a bunch of 183 individual .IMG files along with the relevant .bat file to install the maps into MapSource - so far so good.

When I go into MapSource, I can select the "BlueCharts 2012" map-set and it displays okay, although it's much slower to redraw that BlueCharts 2008
which I also have installed.

The problem I'm having is that when I use the Map Tool to select the relevant map-sections to upload into my GPS unit, I can only select a huge section
of the map, and not the various local maps that I can see when I used BlueCharts 2008. The following screen-shots will hopefully illustrate what I mean:

Here's an example of the Map Tool showing the outlines of the 'sub-sections' of the main map that I can select with BlueCharts 2008:

But when I select BlueCharts 2012, this shows the smallest available map selection:

Is there any way, during the GMapTool conversion-process, that I can have it use smaller 'sub-maps' as per BlueCharts 2008?

No you can't.
The old Bluechaart maps 2008 were made by a very large number of sub-maps (tiles-charts) with very small size and of different scale each one.
Those sub-maps were overlapping and overlaying map layers.
From far away you could see the data form a large scale general chart (ie scale 1:100000) and as you zoomed in, new smaller scale charts (ie 1:50000, 1:25000,.....) became visible with more detail, until you zoomed in to the smallest scale chart for the area.
For the same harbor you could have 5 or 6 charts with different scales for different zoom levels.

The new g2 Bluecharts are made like road or topo maps.
They have much less but bigger in size sub-files that are not overlapping each other.
For the same area you now have two sub-maps, one solid with map data (Mxxxxxxx maps) and the other transparent with depth contours (Fxxxxxxx maps. This is a way to compose a transparent map of depth contours to overlay it above a road map if you delete the Mxxxxxxx maps from the list!)
Now you zoom in on the same sub-file at all zoom levels.
All the data of the previous overlaying and overlapping sub-maps exist in the two sub-maps for the area.

There is nothing you can do to change how the g2 map is made of, it's a different approach to create and view a marine map.

Every time I try to install a map into Basecamp I follow the instructions given for Gmaptool. When I click split it does the job but when I click install.bat it gives an error. First it comes out with "compiling preview map" and the Gmaptool starts with mapset.mp. I close Gmaptool and the command window comes out with the message : File missing: mapset.img, aborting install. I've used the programme before with no problems but not now! I'm sure I'm missing something, but what?

There are several types of sub-maps, not only Mxxxxxxx (marine?) Fxxxxxxx (fishing?), for example Gxxxxxxx Pxxxxxxx Vxxxxxxx Bxxxxxxx ...
Do you know what they are used for?

I do have another couple of quick questions about the conversion process:

What does the "Create TDB for marine map" option on the "Split" page do? Is there any benefit?

Is it worth enabling the "Limit Preview Map" and "Limit Mapset Area"?

Cheers,

Mike.

Mike have you never took a look at GMapTool Help?

Create TDB for marine map - advanced option, GMapTool will create TDB for marine map. Map will be visible in Mapsource and HomePort but not in BaseCamp

Limit preview map - advanced option, restricts the scope of the preview map to values given in S-N-W-E fields. If option "Limit mapset area" is active, preview map will be smaller then ±178.5° longitude and ±89.5° latitude. This parameter was introduced in order to obtain correct compilation of preview map for world base maps.

Thanks a lot!
